Need a little help. Been a few years since I have gotten back into car audio. The issue I am having is after upgrading my rear speakers, I am getting a small thumping like noise when ever I change the volume on my head unit or selecting an option on the head unit. I ran new wire from the rear speakers to the head unit due to having a factory premium system. I did the same thing for the front. The wires are not near the power nor ground cables. Before I added the rear speakers, the front sounded find and their was no feedback. Please not, I am not getting feedback from the motor or anything like that, just the small thumping noise when ever using different functions on the head unit or changing the volume. The ground it good on the head unit. My current set up is a pioneer avh-x4800bs and some basic pioneer front and rear speakers.
